FAN ATTACHMENT FOR ROCKING-CHAIRS.

SPECIFICATION forming part of Letters Patent No. 547,375, dated October1, 1895. Application filed June 20, 1895. Serial No. 55 3,389. (Nomodel.)

To all whom, it may concern:

Be it known that I, WILLIAM J. FERGUSON, a citizen of the United States,residing at Bab timore, in the State of Maryland, have invented certainnew and useful Improvements in Fan Attachments for Rocking-Chairs, ofwhich the following is a specification.

My invention relates to a fan attachment for rocking-chairs, and has forits object to provide a simple fan-operating mechanism comprising alazy-tongs to move the fan when the chair tilts in one direction and aspring to move it when the chair tilts in the reverse direction.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation of a rockingchair embodying my invention.Fig. 2 shows an enlarged detail View of the bracket and operating partsof the fan detached from the chair. Fig. 3 is a view of the same partsshown in Fig. 2, as seen in the transverse direction. Fig. 4 is a viewof the clip which attaches to the rocker and shows the lower part of thelazy-tongs and the rollers. Figs. 5 and 6 show a modified form embodyingmy invention.

The letter A designates the back of a rocking-chair of any preferredstyle, and b the rocker thereof.

Referring to Figs. 1 to 4, inclusive, bracket 0 has two horizontal armsd, each of which serves as a bearing for a shaft E, which carries aheady, that holds the fans g. The head 5 fis adjustable on the shaft bya set-screwf.

The lower part of the bracket 0 is fixed rigidly on a lateral stud h,which fitsloose in an eye it on the upper end of a supporting-bar I,which has a suitable clamp j and set-screw by means of which it may beattached to the back of a rocking-chair, as shown in Fig. 1. It will beseen the supporting-bar I has a fixed position on the chair-back; butthe bracket 0, which carries the fan-shaft, may be tilted. This capacityto tilt enables the bracket to be set at any desired inclination, and aset-screw 72 in the eye by impinging against the stud will hold thebracket wherever it may be set. By thus tilting the bracket 0 andfan-shaft E, as desired, the fans gmay be set to suit the personoccupying the chair. The lateral stud projects at the opposite side ofthe bracket (see Fig. 3) and serves as a fixed spindle, on

which is loosely mounted a grooved pulley or a roller k, which is usedto guide the cord hereinafter mentioned.

A drum or reel Z is rigidly attached to the fan-shaft E between the twobearings d, and one end of the cord m is secured to said drum and passesaround it and back over the said guide-pulley 7t and then down to thelazy-tongs.

A- spiral torsion-spring n surrounds the fanshaft and one end. is madefast to one of the bearings 01 ofthe bracket and the other end made fastto thedrum Z. This spring is arranged so as to wind up or tighten whenthe drum turns, so as to unwind the cord and at the same time the fansare revolved in one directionthat is, when the chair tilts backward-andthe spring relaxes or unwinds, and thereby turns the drum, so as to windup the cord, and at the same time the fans are revolved in the oppositedirectionthat is, when the chair tilts forward.

It will be understood that when the cord m is pulled by the lazy-tongsat the time the chair rocks back the drum Z is thereby caused to turnand the cord unwinds therefrom, and at this time the spring is Wound up.When this backward movement of the chair ceases and the forward movementcommences, the stored-up power of the spring n will relax and cause thefan, and also the drum, to turn in the reverse direction, and thusrewind the cord. Thus a pull on the cord turns the fans in onedirection, and the wound-up spring turns the fans in the oppositedirection.

A lazy-tongs device 0 has a clip p attached to the lowermost pivot q ofsaid lazy-tongs. This clip fits over the rocker b of a chair and issecured thereto by a set-screw p. The

arranged with respect to the rocker that when the chair moves backwardthe lazy-tongs will close down or collapse, and thereby pull on the cordm. This is dueto the depression of the lowermost pivot q and thespreading action of the rollers. When the chair moves forward, thelowermost pivot q is raised and the rollers s, acting as Weights, willstay on the floor, and thereby the lazy-tongs will be extended upward,which movement slackens the cord m and allows it to be rewound on thedrum I.

The modified form shown in Figs. 5 and 6 embodies the leading feature ofmy invention with a simpler construction. Referring to these figures,the letter A designates the back of the rocker, to which thesupporting-bar I is secured by a clamp j. At the top of this bar arebearings 01, in which a fan-shaft E revolves. This shaft carries a headf which holds the fans g. The fan-shaft has a drum Z fixed rigidly onit. The lazy-tongs O are exactly the same as in Figs. 1 and i and areattached to the rocker in the same way and have rollers. A spring at inthis case is a spiral spring and is attached by one end to the chair atsome suitable pointin this case to the rocker. The cord m is wound onceor twice around the drum Z, in order to give suflicient grip thereon toprevent it from slipping, and one end of the cord is attached to thelazy-tongs and the other end to the spring This modification operatesthe same as n the form shown in Fig. 1. When the chair tilts in onedirection, the lazy-tongs act to move the fan, and when it tilts in thereverse direction the spring acts to move the fan.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with a rocking chair of a fan; lazy-tongs connectedwith the fan to move it when the chair tilts in one direction, and aspring connected with the fan to move it when the chair tilts in thereverse direction.

2. The combination with a rocking chair of a revoluble fan carried onthe chair; lazytongs secured to the rocker of the chair and alsoconnected with the fan and the lowermost arms of said lazy-tongs havingrollers which rest on the floor, and aspring connected with the fan,whereby when the chair tilts in one direction the collapse of thelazy-tongs will rotate the fan and when the chair tilts in the reversedirection the spring will rotate the fan.

3. The combination of a rocking chair; a revoluble shaft carried on saidchair and carrying a fan and a winding drum; lazy-tongs secured to therocker of the chair; a cord or equivalent connecting the said windingdrum and lazy-tongs whereby the fan is rotated in one direction when thechair tilts one way, and a spring co-acting with said revoluble shaftand lazy-tongs whereby the fan is rotated in the opposite direction whenthe chair tilts the reverse way.

In testimony whereof I affix my signature in the presence of twowitnesses.
